The object of the invention is to provide a spindle' with a sleeve whichis adapted to be turned or rotated upon the same so that as the undersidethereof becomes flattened or worn from use, the said sleeve may.l beturned so as to present a rounded portion of the surface thereof to thebearing surface of the hub boxing. The sleeve is maintained upon thespindle by means of a nut which engages the same thread as that engagedby the liub nut. The said sleeve is retained against rotary movement bymeans of shoulders or projections formed at the larger end of thespindle and which enter corresponding recesses formed at the inner endof the said sleeve. f l

In the accompanying drawing-Figure l1 is a side el i vation of thespindle showing the sleeve and hub box'- ing in section. Fig. 2.is atransverse sectional view of the parts cut online 2, 2 of Fig. 1.

The spindle 1 is provided at its inner or larger end with` the shouldersor projections 2, 2. The said spindle lits snugly within the sleeve 3,said 'sleeve having at its inner end the recesses 4 which receive theshoulders 2 and retain the said sleeve frbrn rotary movement withrelation tol the spindle 1. The outer end of `the said spindle is screwthreaded in the usual manner as at 5 and the nut 6 engages the saidthread 5. The diameter oil the nut 6 is equivalent to or less than thediameter oi tlieouter end of the sleeve 3. ,The said sleeve is provi'ledwith the usual lubricant'groove 7. rllhe hub Specification. of LettersPatent. -A r r n 1A tze 1906i` in'. 2.4 o. pp ica ion e( ugus/ ,p 0A

boxing 8 receivesihe said sleeve 3 and the hub nut 9 engages the thread5 of the spindle 1 and is provided with the shoulder 1'() which bearsagainst the outer end of the hub box 8. T he said nut 9'is also.provided With a recess 11 which receives the nut 6. v From'the foregoingdescription it is obvious that the sleeve 3 wears or becomes flattenedupon its under surface, due to friction with the hub boxing the nut 6may be removed and the sleeve 3 slipped longitudinal lyof thespindle 1until tile recesses 4 are beyond the shoulders 2 when the said sleeve 3may be partially rotated and the recesses 4 rengaged with theshoulders2,

v thus bringing another portionof the surface of the sleeve 3 directlyunder'the lower surface'of the spindle 1.

Aflso the sleeve when it is wornout may be removed entirely and a newsleeve of similar design substituted therefor.

Having described my invention what I claim as new and desire to securelby Letters Patent isz- A device such :is described#comprising n spindlehaving `:i threaded tend, :l sleeve receiving said spindle, unenns forretaining said sleeve. in severatdiiferent positions against rotationupon the spindle., n nut'engzigliig the thread o'i the 'spindle :indbearing directly against the end of the sleeve.

the diameter of said nut being less than .the diameter et' the:idjnc'entend of tlie sleeve., u huh box journnled upon said sleeve :indlinvinif itsoulor cnil [lush with the outer' end.ol' the latter, :i hubnut enguglni.:4 the tlirend oi' ilie spindlel und having :i rei'esswhich receives said mit and which is of greater depth thzln thethickness' oi' the nut, said hub mit bearingwlireeily against the endet' the hul) bex.
